OCEAN BOTTOM SEISMICS: Impact on field development
{"Image DocumentName": "OCEAN BOTTOM SEISMICS: Impact on field development", "Image ImageDescription": "Mark Thompson, B\u00f8rge Arntsen  and Lasse Amundsen. Statoil R&D. During the last 10 years Statoil has acquired a Large number of Ocean Bottom Seismic (or OBS for short ) surveys. In almost all cases have the quality of the subsurface images been much better than the images from corresponding streamer surveys. This has been mostly attributed to the larger cross-line offsets and the larger azimuth angles between source and receiver used in OBS surveys, relative to conventional streamer surveys where the cross-line offsets and azimuths are comparatively smaller. Recently attempts have been made to increase the cross-line offsets in streamer surveys, so-called wide-azimuth towed streamer (WATS) surveys. I thought it would be interesting to share some of the experienec we have had with OBS surveys, which have geometries quite close to some of the proposed wide-azimuth streamer surveys.
